Description

Technical Field

[0001] The utility model relates to the technical field of pulleys, in particular to a one-way pulley. Background Art

[0002] Pulleys, which belong to the disc-hub category, are generally relatively large in size and are typically manufactured using casting or forging. They are primarily used in applications where long-distance power transmission is required, such as the output of power from small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machines, some low-horsepower motorcycles, agricultural machinery, air compressors, speed reducers, reducers, generators, cotton gins, and more.

[0003] The existing pulley is directly installed on the drive shaft of the active mechanism. The pulley will rotate in both directions along with the drive shaft. However, some transmission equipment does not allow reverse rotation because reverse rotation of the equipment may cause major production accidents and cause irreversible damage to the equipment itself.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the above background technology, there is a problem in the prior art that the pulley is directly installed on the transmission shaft of the active mechanism, and the pulley rotates in both positive and negative directions along with the transmission shaft.

[0006] The utility model discloses a one-way pulley, comprising a driving wheel, wherein a mounting groove, a slot and a rotation groove are provided inside the driving wheel, a ratchet is fixedly connected to the inner wall of the mounting groove, and equidistantly arranged clamping grooves are provided inside the ratchet, and a support shaft is rotatably connected to the inner wall of the slot, the outer surface of the support shaft is fixedly connected to a mounting plate and a mounting ring, the outer surface of the mounting ring is fixedly connected to a support column, the outer surface of the support column is slidably connected to a connecting block, the end of the connecting block away from the support column is fixedly connected to a clamping block, and a spring is installed on a side of the connecting block away from the clamping block.

[0007] Furthermore, one end of the spring away from the connecting block is fixedly connected to the mounting ring, and the support column is located inside the spring.

[0008] Furthermore, the outer surface of the mounting plate is fixedly connected to two fixing blocks, a sliding groove is provided inside each of the fixing blocks, and the outer surface of the connecting block is slidably connected to each sliding groove.

[0009] Furthermore, a bearing is fixedly mounted on the outer surface of the support shaft, and the outer surface of the bearing is in rotational contact with the rotation groove.

[0010] Furthermore, a driven wheel is provided on the left side of the driving wheel, and trapezoidal grooves arranged at equal distances are provided inside the driving wheel and the driven wheel.

[0011] Furthermore, a belt body is provided on the outer surface of the driving wheel, and two trapezoidal grooves arranged at equal distances are provided inside the belt body.

[0012] Furthermore, the belt body is sleeved with the interior of each trapezoidal groove 1, and the driving wheel is transmission-connected with the driven wheel through the sleeved connection between the belt body and the trapezoidal groove 1.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The utility model is provided with components such as a ratchet, a card block, a support column and a spring. When the device is used, when the motor drives the support shaft to rotate, the support shaft will drive the mounting plate and the mounting ring to rotate, and at the same time, the mounting plate will drive the connecting block and the card block to rotate. When the card block rotates, the engagement between the card block and the card slot drives the ratchet and the driving wheel to rotate. When the support shaft stops rotating or reverses, the card block will drive the connecting block to be retracted toward the support shaft along the card slot, the card block will cancel the engagement with the card slot, and the support shaft will also cancel the control of the driving wheel, thereby achieving the effect that the device can control the pulley to rotate in one direction according to demand.

[0015] 2. The utility model is provided with components such as a support shaft, a slot, a rotating groove and a bearing. When the device is used, when the motor drives the support shaft to rotate inside the driving wheel, the support shaft will drive the bearing to rotate inside the driving wheel. Through the contact between the bearing and the driving wheel, the friction generated when the support shaft and the driving wheel rotate is reduced and the heat generated by the friction is discharged, thereby increasing the service life of the pulley rotating structure.

[0023] See also Figure 1-Figure 4 The utility model is a one-way pulley, including a driving wheel 1, which can provide power, output torque and power through the setting of the driving wheel 1. Specifically, the interior of the driving wheel 1 is provided with a mounting groove 2, a slot 5 and a rotation groove 15. The mounting groove 2 is convenient for installing the ratchet 3, and the slot 5 is convenient for installing the support shaft 6 inside the driving wheel 1. The rotation groove 15 is convenient for supporting the driving wheel 1 with the bearing 16. The inner wall of the mounting groove 2 is fixedly connected with the ratchet 3. When the ratchet 3 rotates, the driving wheel 1 can be controlled to rotate synchronously. The interior of the ratchet 3 is provided with equidistantly arranged card slots 4. The card slots 4 are convenient for the ratchet 3 to be clamped with the card block 11.

[0024] The outer surface of the supporting shaft 6 is fixedly connected to the mounting plate 7 and the mounting ring 8. When the supporting shaft 6 rotates, the mounting plate 7 and the mounting ring 8 are driven to rotate synchronously. The outer surface of the mounting ring 8 is fixedly connected to the supporting column 9. The outer surface of the supporting column 9 is slidably connected to the connecting block 10. The end of the connecting block 10 away from the supporting column 9 is fixedly connected to the clamping block 11. When the mounting plate 7 and the mounting ring 8 rotate, the clamping block 11 is driven to rotate through the supporting column 9 and the connecting block 10. When the clamping block 11 rotates, it drives the ratchet 3 and the driving wheel 1 to rotate by engaging with the card slot 4. A spring 14 is installed on the side of the connecting block 10 away from the clamping block 11. The spring 14 can help the clamping block 11 and the connecting block 10 to reset after the card slot 4 pushes the clamping block 11 and the connecting block 10 to move.

[0025] See also Figure 1 and Figure 2A driven wheel 20 is provided on the left side of the driving wheel 1. The driven wheel 20 can be rotated through a transmission connection with the driving wheel 1. The driven wheel 20 is smaller than the driving wheel to increase the rotation speed. Specifically, the interior of the driving wheel 1 and the driven wheel 20 are provided with equally spaced trapezoidal grooves 17. The opened trapezoidal grooves 17 can be conveniently connected with the belt body 18. The outer surface of the driving wheel 1 is provided with a belt body 18. The friction force of the belt body 18 transmits the rotational force of the driving wheel 1 to the driven wheel 20, thereby controlling the rotation of the driven wheel 20. The interior of the belt body 18 is provided with equally spaced trapezoidal grooves 2 19. The opened trapezoidal grooves 2 19 and the trapezoidal grooves 17 can be suitable for high-load, high-speed transmission equipment.

[0026] In a preferred embodiment, the belt body 18 is engaged with the inside of each trapezoidal groove 17. Through the engagement of the belt body 18 with the trapezoidal groove 17, the driving wheel 1 and the driven wheel 20 can drive the belt body 18 to rotate when they rotate. Specifically, the driving wheel 1 is connected to the driven wheel 20 through the engagement of the belt body 18 with the trapezoidal groove 17. When the driving wheel 1 rotates, the driven wheel 20 can be driven to rotate through the belt body 18.

[0027] See also Figure 1 and Figure 3 A bearing 16 is fixedly installed on the outer surface of the support shaft 6. The bearing 16 can provide the main support for the support shaft 6 to the driving wheel 1. The outer surface of the bearing 16 is in rotational contact with the rotating groove 15. The rotating connection between the bearing 16 and the rotating groove 15 can reduce the friction between the driving wheel 1 and the support shaft 6, and discharge the heat generated when the support shaft 6 rotates.

[0028] See also Figure 3 and Figure 4 The outer surface of the mounting plate 7 is fixedly connected to two fixed blocks 12. The two fixed blocks 12 can facilitate the installation of the connecting block 10. A sliding groove 13 is provided inside each fixed block 12. The sliding groove 13 can facilitate the movement of the connecting block 10 on the mounting plate 7. The outer surface of the connecting block 10 is slidably connected to each sliding groove 13.

[0029] See also Figure 1 and Figure 4 The end of the spring 14 away from the connecting block 10 is fixedly connected to the mounting ring 8. The connection between the spring 14 and the mounting ring 8 can facilitate the fixation of the spring 14. Specifically, the support column 9 is located inside the spring 14. By installing the support column 9 inside the spring 14, the conflict between the spring 14 and the support column 9 can be avoided. The elastic force of the spring 14 can help the connecting block 10 to reset the card block 11.
